The only one I ever had that died was for a ink-jet printer. By then the printer was so old there were no replacements.
Anyway, since then I plug the new printer into a powerstrip that keep shut off except when using the printer.
However, I have a bunch of other devices using these plug-in bricks. Even when not used, they remain warm when plugged in. I assume that this adversly affects their life, but just how much?
Somehow I expect the wear is minimal, but no luck Googling this, so anybody know for sure what the score is on their lifespan left pluged in?
Like 30 years unplugged when not needed, and 20 years live all the time?
